MASSACHUSETTS, ASSIGNOR TO THE LOWELL MACHINE SHOP, OF SAME PLACE.

COlLER-HEAD.

SPECIFICATION forming part of Letters Patent No. 641,388, dated January16, 1900.

Application filed September 18, 1899.' Serial No. 730,802. (No model.)

T0 all whom it may concern:

Be it known that I, CHARLES'L. HILDRETH, of Lowell, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in CoileryHeads, of Which the following is aspecification.

My invention relates to coiler-heads having an openin g in the top ofthe casing,which may be closed or may be opened readily to expose theoperating mechanism of the coiler.

The object of my invention is to Amake it easy by means of a simplifiedconstruction to inspect or to oil that mechanism without stopping it orbreaking or twisting the sliver or causing the sliver to gather iiyingsor dust.

Heretofore in such coiler-heads the trumpet has been made integral withor has been attached to the slide or cover for the opening and has beenrevoluble therewith to cover and uncover the openingin the casing,thereby unnecessarily twisting the sliver during the opening or closingthereof. Moreover, the flyings and dust which have collected upon thetrumpet and upon the slide or cover While they are not in motion havebeen caught by and incorporated into the moving sliver and carried bythe sliver into. the coiler-can as the trumpet and slide or cover havepassed beneath it. The soiling of the sliver which occurs during theuncovering of the opening by ordinary operatives Who exercise onlyordinary care is objectionable and is obviated by my invention, which isrepresented in Figures l, 2, 3, 4, and 5 and is of simplifiedconstruction.

Fig. l is a plan of the coverof the coilerl head with the opening in thetop thereof partially uncovered. Fig. 2 is a longitudinal section of thecover through the uncovered opening. Fig. 3 is an end elevation of thecover of the coiler-head with the opening in the top thereofpartiallyuncovered. Fig. 4 is a vertical longitudinal section of thecoilerhead, upon a reduced scale, showing the mechanism which requiresinspection and oiling, but which is of usual construction and forms nopart of this invention. Fig. 5 is a plan, upon a reduced scale, of theslide or cover d, showing the perforation e.

Similar letters refer to similar parts in the different views.

a represents the coiler-cover; b, the back sliver-guide; c, the trumpetsliver guide,

through which the sliver passes to the operating mechanism; d, the slideor cover for covering or uncovering the opening; ff and f f', the meansused for fastening the trumpet and back sliver-guides to the cover; g,

the opening in the cover through which the 6o operating mechanism can beinspected or oiled; h, a rabbet in b, which receives a part of d whenthe opening is covered, and c" a rabbet in o, which receives a part of dwhether the opening is covered or uncovered. The

cover is perforated at e. to receive the trumpet sliver-guide aboutwhich it rotates. Preferably the perforation is cylindrical.

The trumpet and back sliver-guides are made thicker than is usual, andthe sliver is 7o thereby raised so high above the slide or cover d thatthe slide or cover can be moved to cover or to uncover the openingwithout bringing the flyings or dust which have collected thereupon intothe path of the moving cover or upon the top of the trumpet sliverguideare not during the uncovering of the opening caught by and incorporatedinto the moving sliver and carried into the coiler-can.

I claim- The combination with the casing of a coiler- 9o head containingmechanism and having in its top an opening, of trumpet and backslivervguides each of which is fixed to the said top and is rabbeted toreceive a cover for the Aopening and a cover which is perforated toreceive the trumpet sliver-guide and is rotatably mounted upon the topof the casing in the rabbet of that guide to cover the opening and fitinto the rabbet at the back sliverguide and to uncover the opening inthe cas- 10o lng, substantially as described.

In testimony whereof I affix my signature in the presence of twowitnesses.
